catheter pinch off

central vascular access device

umbrella term that includes a variety of catheters, cannulas & infusion ports that allow intermittent or continuous central access to a bv; a device usually inserted into subclavian or jugular vein w/ distal tip resting in the SVC just above the RA & used for long-term IV therapy or parenteral nutrition

dysrhythmia

embolus

extravasation

seepage or introduction of fluid, such as intravenous fluid, into the tissues surrounding a blood vessel; sometimes used interchangeably with infiltration but more accurately describes catheter dislodgement with medication infusing into the tissues and causing actual or potential tissue damage

implanted vascular access device

incompatibility

lack of harmonious coexistence; used to refer to two or more medications or solutions that cannot be given simultaneously or mixed without changing the effects of each other or causing any new responses not seen with any of the drugs or solutions administered alone

phlebitis

pneumothorax

positive pressure injection cap

cap attached to the end of a catheter that exerts positive pressure into the line after flushing and removing the syringe, thus preventing backflow of blood into the catheter and reducing the risk of occlusion

turbulent flushing

valsalva maneuver

forceful exhalation against closed glottis, which increases intrathoracic pressure thus interferes w/ return of venous blood to heart; performed with central line insertion to create a positive phase in central venous pressure, thus reducing the risk of air being drawn into the central circulation and creating an air embolus
